Can-type heat exchanger

A can type of heat exchanger comprising:

• a housing formed as a cylinder with one side closed and another side opened, having a mounting space at the inside, integrally formed with a mounting portion provided in a lateral side of the housing and connected with the mounting space, and formed with at least one inlet and at least one outlet provided in the closed one side and the lateral side respectively, of the housing;
• a heat dissipation unit mounted in the mounting space of the housing, provided with connecting lines alternately formed by stacking a plurality of plates, one of the connecting lines connected to the mounting space, receiving operating fluids from the inlet, and the operating fluids heat-exchanging with each other;
• a separating plate separating the mounting space and inside of the mounting portion, connected to the inlet formed on the mounting portion and the outlet formed on the lateral side of the housing, and forming a bypass passageway in addition to the connecting line of the heat dissipation unit;
• and
• a valve unit that is mounted at the inlet formed in the mounting portion and penetrates the separating plate in the mounting portion, selectively opening and closing the mounting space or the bypass passageway separated by the separating plate using linear displacement which is generated when expansion and contraction occur according to temperature of the coolant flowing from the inlet, and adjusting flow of the operating fluids.
